Retractable plunger design for injection control device for proportional injection extraction during the syringe's insertion extraction

Abstract

An injection control device (ICD) for a syringe, injects/extracts material into/from at a rate controllably proportional to the rate of movement of the syringe. A transmission reference member is extendable outward from the ICD body, being connected to a transmission system/clutch which has an engage/disengage trigger for independent movement of a plunger arm. The ICD, via the transmission translates motion from movement of the body, in relation to a fixed state of the transmission reference member, to action on the plunger of an accommodated syringe. The clutch also allows the transmission reference member to be positioned, without transferring power to the transmission system.
